To all whom it may concern: 7

Be it known that I, WILHELM :KIIELING, a subject of the German Emperor, IBSIClIIIg at F rankfort-on-the-Main, Germany, have 1nvented a new and useful Improvement 111 Pitmen for Internal-Combustion Engines with Rotating Cylinders; and I do hereby declare the following to be a full, clear, and eXact description of the same.

The present invention relates to improvements in pitmen or connectlng rod ends for internal combustion engines with rotatlng cylinders and has for its object so to construct and arrange the connecting rod ends that they occupy the least possible space and at the same time inclose the cams for the actuation of the inlet valves mounted in the pistons.

The invention is illustrated in the accompanying drawings, in which,

Figures 1, 2, 3 are separate connecting rods in views at right angles to one another, Fig. 4 shows one half of the main connecting rod with collar, Fig. 5 is a section through the collar according to Fig. 4, Fig. 6 represents an elevation of one group of connecting rod ends united in the collar of the one half of the main connecting rod, Fig. 7 is a section through the connecting rod ends and shows the arrangement of the connecting rodends in two groups on the crank pm. Fig. 8 shows the two halves of the main connecting rod secured together.

As shown in Fig. 7 the crank shaft 3 of any known construction and forming part of any known type of internal combustion engines with rotating cylinders carrles a sleeve 4 having cams 5 adapted to control the movement of the inlet valves (not shown) by the means of spindles 31 arranged in the connecting rods 32, of which only the ends are illustrated. The sleeve 4 is rotated in any convenient manner, for instance by the means of a pinion 7 driven by means of any suitable rotating part of the engine.

If the engine has seven cylinders, as is assumed in the case illustrated, the connecting rods are' divided into two groups of three each and a main connecting rod 33, which is divided longitudinally and each half of the same is connected with a collar 34 (Figs. 4 and 5) in which the annular ends of the connecting rods united to one group are concentrically arranged (Fig. 6).

The connection between the rod 33 and the collar 34 is enlarged as shown at 50 (Fig. 4) 'and'is provided with holes 51 adapted to be engaged by screw bolts 52 (Fig. 8). The opposite end of the main conneotingrod,through which the bolt of the piston is fitted, is provided with an enlargement 53 with holes 54 adapted to be engaged by screw bolts 55, as will be seen Y in Fig. 8. 43 is an annular slot into which the enlarged ends of the other connecting rods fit. 44 is an annular flange adapted to be engaged by the ball bearings 45 (Fig. 7

Into the collar 34 the ring 35 of the connecting rod 32 (Fig. 1) is first inserted. Into this ring is fitted the ring 36 of the rod 32 (Fig. 2) and into the same the ring 37 (Fig. 3) of the connecting rod 32. The ring 37 is provided with a flange 38 for the insertion of a roller bearing 39 (Fig. 7). The rings 35 and 36 are formed with recesses 40 to permit the crosspieces or webs 41 arranged between the ring 37 and its rod 32 and between the ring 36 and its rod 32 to move therein. To take up the pressure of explosion laterally projecting 'BX- tensions 42 are provided on each connecting rod 32 which extensions slide in annular grooves 43in both collars (see the connecting rod 32* in Fig. 7).

After each group of connecting rods is inserted into a collar 34 both collars and therewith the halves of the main connecting rod 33 are connected with one another, for instance by means of bolts screwed through the halves of the main connecting rod. The extensions 42 of the connecting rods 32 within one collar engage in the groove 43 of both collars.

What I claim is 1. The combination in an internal combustion engine with rotating cylinders, of p a crank, a plurality of pitmen provided with annular heads engaging one over the other and around the crank, the heads being arranged in two groups, and collars inclosing the groups of concentrically arranged heads.

2. The combination in an internal combustion engine with rotating cylinders, of a crank, a plurality of pitmen provided with annular heads engaging one over the other and around the crank, the heads being arranged in two groups, a main rod comprising a pair of cooperating members, each member provided with a collar inclosing a group of said concentric heads; and means for fastening together said cooperating members.

3. The combination in an internal combustion engine with rotating cylinders, of a crank, a plurality of: pitmen provided with annular heads engaging one over the other and around the crank, the heads being arranged in two groups, and a main rod having two collars each concentric with one of the respective groups of heads.

4. The combination in an internal combustion engine with rotating cylinders, of a copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
